    Abstract: Steel cord includes a first group and a second group. The second group is helically twisted around the first group with a cord twisting step. The first group includes a first number of first steel filaments. The first number ranges between three and eight. The second group comprises a second number of second steel filaments. The second number is equal to or greater than the first number. The first filaments having a twist step greater than 300 mm. At least one of the second filaments is polygonally performed in order to allow rubber penetration.

    Abstract: A tire cord having core filaments preformed into a helical configuration while maintaining the core filaments in a parallel, side-by-side relationship. The core filaments are not twisted or stranded together. High tensile strength sheath filaments are also preformed into a flattened helical configuration so that the sheath filaments can be wrapped around the side-by-side core filaments such that the sheath filaments do not put such tension on the core filaments as to cause the core filaments to bunch. The core filaments are maintained in a flat, side-by-side configation so that no voids are formed and rubber can penetrate into the tire cord. The core filaments may number from three to six and the sheath filaments from one to seven. The cross-section of the tire cord is flattened and confined within an oval-shaped outer bound, the oval outer bound being characterized by a major axis and a minor axis. It is desirable that the minor axis be no greater than 60% of the major axis to created the appropriate difference in the bending modulus of the tire cord in the horizontal versus the vertical direction.

    Abstract: A bead ring for tubeless pneumatic tires is disclosed. The bead ring includes a core formed by a plurality of wires or a solid shaped structure and is constructed of a non-elastic material. A plurality of layers of helically wound, closely spaced wires surround the core, and the wires of each layer are oppositely pitched with respect to the wires of adjacent layers. The combination of the core and the layers of wires form a bead bundle having a generally semi-circular cross-section. This abstract is not to be taken either as a complete exposition or as a limitation of the present invention. The full nature and extent of the invention is discernible only by reference to, and from, the entire disclosure.
